I have an open channel with some inclination i.e. negative slope.
I have done its modelling as well as meshing. In fluent, i have done following operations- (1) General- Pressure based solver and steady flow Model- volume of fluid, checked open channel flow and body implicit force (2) checked energy equation (3) selected k-epsilon model (4) Phases- primary phase- water secondary phase- air (5) Boundary conditions- for velocity inlet: in momentum, for mixture, i have given zero gauge pressure and zero velocity. Also i have given hydraulic intensity 10% and hydraulic diameter A/P. for pressure outlet: same as that for velocity inlet Symmetry walls: default conditions (6) Solution method- PISO and all default conditions Is there something else which i am missing because i am not getting the correct velocity profile although pressure profile which i am getting, is correct to be linear? Please help me. Its an urgent. |

What ever is the volume fraction of water, i am getting the same velocity profile against depth, how this can be possible?
